| Microsoft DirectX 8.1 (C++) |
The GetLoader method retrieves a pointer to the loader object that created the stream.
Syntax
HRESULT GetLoader8(
IDirectMusicLoader ** ppLoader
);
Parameters
ppLoader
Address of a variable that receives the IDirectMusicLoader interface pointer. Use QueryInterface to obtain IDirectMusicLoader8. The reference count of the interface is incremented.
Return Values
If the method succeeds, the return value is S_OK.
If it fails, the method can return E_NOINTERFACE.
Remarks
The following code example is from a file parser that finds a reference to an object that needs to be accessed by the loader.
HRESULT myGetReferencedObject(
DMUS_OBJECTDESC *pDesc, // Descriptor already prepared.
IStream *pIStream, // Stream being parsed.
IDirectMusicObject **ppIObject) // Object to be accessed.
{
IDirectMusicGetLoader *pIGetLoader;
IDirectMusicLoader *pILoader;
ppIObject = NULL;
HRESULT hr = pIStream->QueryInterface(
IID_IDirectMusicGetLoader,
(void **) &pIGetLoader );
if (SUCCEEDED(hr))
{
hr = pIGetLoader->GetLoader(&pILoader);
if (SUCCEEDED(hr))
{
hr = pILoader->GetObject(pDesc, IID_DirectMusicLoader,
(void**) ppIObject);
pILoader->Release();
}
pIGetLoader->Release();
}
return hr;
}
